Printer ink cartridges — laser streaks are not an inkjet clean
Printer ink
Gray or black streaks on a laser are drum or toner issues — not a reason to burn printer ink cartridges with inkjet clean cycles. Match the engine type first.

Burning printer ink cartridges with clean cycles only helps inkjet heads. Gray bands or toner streaks on a laser point at drum, fuser, or toner distribution — running an inkjet clean on the wrong engine wastes ink and solves nothing.
Laser streaks are not an inkjet printer ink clean cycle
- Confirm engine type on the door label or model plate: inkjet (liquid printer ink cartridges / tanks) vs laser (toner cartridge + drum).
- If pages show dry gray bands, ghosting, or toner smear on a laser, skip inkjet nozzle cleans entirely — use the laser’s own drum/toner diagnostics.
- On inkjets, match the exact ink cartridge number (standard vs XL) before any clean; cleans do not fix a wrong number or empty stall.
- Stop stacking cleans when the machine is laser-only or the status page already marks the stall empty — switch to the correct service path.
If the model is laser and streaks remain after reseating toner per the manual, stop DIY cleans and use drum/toner service messages — not inkjet advice.
